"Them throwing people in the jail cells made me think right away that it was a mistake from the start. They maybe thought they could control it more, and perhaps the spell has become refined since then. My guess would be worlds rather than individuals are specified."

"But they don't know how to send us back or they would have done it before. They are truly out of their depth."

Istredd is not being critical in the way people might be of Thorne in terms of the monarchy or their power dynamics. He is saying it all very rationally. Mages are fools, he knows that much from his own experience. So focused on their own power.

"It might be worthwhile to try to find that spell. I doubt it would be easy though."
